Sphero's tiny, motorized BB-8 droid (based on the company's well-known ball robot design) was the Star Wars toy to have when Episode VII hit theaters last year. It's become less of a hot commodity since then, but Sphero keeps adding new things to do with the toy, and now you can actually find it on store shelves. The miniature astromech was just a little past the impulse buy range at $150 retail, though it looks like most retailers have taken it down to $130 or so. Today Amazon has the toy for even less.
